(KGTV) - Caltrans announced freeway closures on I-5, I-15 and SR-163 to do road work this month.
State Route 163 will have closures in Mission Valley starting Monday night. Residents and businesses may hear jackhammering and truck back-up alarms.
All lanes of north 163 will be closed between I-8 and Genessee Avenue Monday, Tuesday and possibly Wednesday nights 11:30 p.m. to 5 a.m.
The Genessee on-ramp to north 163 will remain open. Other drivers will be detoured to I-8 and I-805.
I-15 will be closed at SR-76 in Escondido during daytime hours Tuesday. The north I-15 connector will be shut down from 9 a.m. to 2:30 p.m. for road maintenance.
Signs will be posted directing motorists on northbound I-15 to exit at Mission Road/Old 395, then turn left to southbound I-15 to access SR-76.
Starting Sunday night and going until May 30, construction crews will close either northbound or southbound lanes of I-5 overnight to begin construction of the Mid-Coast Trolley.
Drivers will see heavy equipment and machinery on the freeway, and residents can expect to hear loud construction noise during the closures.
The project will start with a large support column for the trolley bridge in the freeway center divider.
The trolley is being built to extend the Blue Line eleven miles north from the Old Town Transit Center to University City, running through Mission Bay Park, the VA Medical Center, UC San Diego and Westfield University Town Center Mall.
The Mid-Coast Trolley is expected to start running in fall 2021.
